All the links on sidebar, heading, sub-heading & dates beside posts don’t meet WCAG standards for accessible text.
In my opinion the sub-heading’s contrast must be increased, other text looks okay to me but again they don’t meet the guidelines so may be inaccessible for other people with not good vision.
By sub-heading I mean this text: IFF is your advocate to protect and advance constitutional freedoms in a digital society (Contrast: 2.97)
